Instrumental computer system for distance learning
(Українські технології, 2006) Semotyuk, V.
The structure of the system for the study of notions and terms of subject domain with an unclear structure is considered, in particular, the structure of data-base system. The proposed system allows to create new educational courses regardless of subject domain, to automatize teaching of users after these courses, to carry out diagnostics of knowledge and manage teaching. The system provides the possibility of the independent study of notions and terms of a several disciplines, the support of the simultaneous teaching of a several users, the verification of rightness of pupil’s answers of pupil on a template, the addition of new educational courses without modification of the code of the program, the use of the editor of educational courses.
Self-organising map as a tool of modelling the design parameters of microelectronics devices for ensuring the specified temperature condition
(Українські технології, 2006) Bilas, O.; Levus, E.; Yakovyna, V.
Using Kohonen maps the analysis and visualisation of thermal management task for flip-chip microelectronic devices have been carried out. The advantages of neural networks techniques over most common ones are demonstrated. The technique is very promising for making a prediction of device parameters for ensuring the specified temperature conditions.

Ways of improving comprehension through discourse processing for applied linguistics students
(Українські технології, 2006) Andreichuk, N.; Karamysheva, I.
The field of discourse processing offers some solutions to the challenge of promoting deep comprehension during learning. The present article sketches the basic components of discourse processing mechanisms, such as constructing explanations, asking deep-reasoning questions, tutoring, and subsequently points out how such mechanisms can be recruited to improve deep comprehension of the study material. The practical mission is viewed as designing of software (both the programming and the linguistic parts), modeling the pointed out mechanisms, which is suggested to become a part of the student-teacher research work carried out in the field of Applied Linguistics.
